ULTRA-PLUS Training Collar with Center Plate, Assembly Chain, and Swivel Ring - Stainless Steel Black

I have a Dogo Argentino and was useing a 3.0 prong collar it just was not doing the job. Now that I ordered the 4.0 my boy is perfect on his walks. Once he pulls the slightest bit he automatically corrects and comes into a heel I do not even give pressure it's his own pulling that corrects him. I was told from K9 trainers to use a 3.0 and it was just too small for this dog. He is now a year and 4 months old and it's the one tool that really keeps him popping without me doing a thing. Sizing the prong collar properly is really important don't take it lightly it's the matter of having a great behave dog compared to one that behaves once in awhile. My dog looks forward to putting it on to go out for walks. Win,win.

I have a 100lb Great Pyrenees that protects my sheep and is a big puller whenever I take him anywhere on a leash. Was told about Hem Springer and their prong collars. Decided to get one. Got the 4mm (biggest). In one 5 minute training session to get him used to it, he some how magically turned into a completely different dog! I did watch a few YouTube videos to ensure I was putting the collar on correctly and how to train him with the prong collar. The difference is night and day. Hen Springer just got a customer for life. Its rugged, durable, quality, craftsmanship, ease of use, etc all get 5 stars. These folks know what they are doing! Thanks for making such an astounding product!!

It is not company policy to use the prong collars on young puppies. They gave me the email of the powers to be. They responded and gave authorization to purchase the collar. Customer service was great.

This prong collar is built with outstanding quality—sturdy, smooth, and comfortable for my dog. The difference on walks was immediate: no more pulling, just calm, controlled movement. Easy to adjust, humane, and incredibly effective. Worth every penny!

I bought this at the recommendation of my trainer as a tool to help my dog over a training hump. It’s much better quality than others i looked at and we’re back to making progress with our training.
